Few studies have examined the impact of age on reactivity to concurrent think-aloud (TA) verbal reports. An initial study with 30 younger and 31 older adults revealed that thinking aloud improves older adult performance on a short form of the Raven's Matrices (Bors & Stokes, 1998, Educational and Psychological Measurement, 58, p. 382) but did not affect other tasks. In the replication experimen...

Decision theory distinguishes between risky prospects, where the probabilities associated with the possible outcomes are assumed to be known, and uncertain prospects, where these probabilities are not assumed to be known. Studies of choice between risky prospects have suggested a nonlinear transformation of the probability scale that overweights low probabilities and underweights moderate and h...

Many people self-weigh and many interventions addressing weight-related problems such as obesity promote self-weighing. However, while self-weighing has been associated with weight loss, there is mixed evidence regarding the psychological impact of this behaviour. The present review aimed to quantify the relationship between self-weighing and: (i) affect (e.g., anxiety, depression); (ii) psycho...

The problem of designing an Extended Regulator is defined as designing an algorithm that can adjust the optimal regulator gains for a time-variant linear system appropriately to match the variations in system parameters with time. Due to conditions of positive definiteness on the unknown variable in the Riccati equation for quadratic optimal control it is possible to show that repetitive iterat...

BACKGROUND Frequent self-weighing is associated with better weight loss and maintenance among adults. Emerging adults ages 18-25 rarely enroll in behavioural weight loss trials, and thus, little is known about their willingness to engage in frequent self-weighing and its association with weight loss in this age group. PURPOSE The purpose of this study is to examine the frequency of self-weigh...

A field experiment was conducted to study the consumptive use of water leaf (Talinum triangulare) on a constructed small scale combined weighing and non-weighing Lysimeter. This considered design construction lysimeter that characteristics non-weighing. The main components facility are mild steel, load cell, Arduino nano, micro secure digital (Micro SD) card, liquid crystal display (LCD) screen...

Let 4n2 be the order of a Bush-type Hadamard matrix with q = (2n − 1)2 a prime power. It is shown that there is a weighing matrix W (4(q + qm−1 + · · ·+ q + 1)n, 4qn) which includes two symmetric designs with the Ionin–type parameters ν = 4(q + qm−1 + · · ·+ q + 1)n, κ = q(2n − n), λ = q(n − n) for every positive integer m. Noting that Bush–type Hadamard matrices of order 16n2 exist for all n f...

This paper studies the computationally diicult problem of nding a largest j-dimensional simplex in a given d-dimensional cube. The case in which j = d is of special interest, for it is equivalent to the Hadamard maximum determinant problem; it has been solved for innnitely many values of d but not for d = 14. (The subcase in which j = d 3 (mod 4) subsumes the famous problem on the existence of ...

A portable luminescence spectrofluorometer weighing only 1.5 kg that uses multiple light emitting diodes (LEDs) as excitation sources was developed and evaluated. Excitation using a sequence of seven individual broad-band LED emission sources enabled the generation of excitation-emission spectra using a light weight (<1.5 kg) spectrometer. Limits of detection for rhodamine 6G, rhodamine B, and ...
